DLL error

My wife has been given an oldish laptop (W95)
which she is going to use for Word and e-mails.

The anti-virus was months out of date, and I have sorted that, and I have also installed LNS. However, although it appeared to install without error, when you try to run it I get the following error 'The FWAPI.DLL file is linked to missing export MFC42.DLL:6467.

If the error you have is one of these:
- The FWAPI file is linked to missing export MFC42.DLL:6467
- The LOOKNSTOP.EXE file is linked to missing export: 6905
- The ordinal 6905 could not be located in the dynamic link library MFC42.DLL

The MFC42.dll file of your Windows® configuration is a bit too old.
You will find a more recent version here: http://www.looknstop.com/mfc42.zip To update this file, quit all applications. The file mfc42.dll file is in the c:\windows\system folder. Rename it to mfc42.old, and then unzip the new file in c:\windows\system. If you can not rename it, try again after restarting your computer."
